TECHNICAL FIELD

The present invention pertains to disable a electrical circuit in amobile vehicle or equipment. This invention works in conjunction withour previous Patent, EMERGENCY SHUTOFF SYSTEM FOR POWER MACHINERY,WIRELESS MONITORING SYSTEMS, AND EMERGENCY SHUTOFF METHODS. U.S. Pat.No. 7,012,519

BACKGROUND OF THE INVENTION

When our Patent was granted, the simple way to connect our unit to a gasengine was at the coil circuit and with a diesel engine was at theinjector pump solenoid circuit. Either circuit is controlled by theignition key. Turn on the ignition key in either case, the engines willstart and run. With our unit; powered by these circuits, the key can beon, engine running and our unit can shut off the engine while the key isin the ON position. This has proven to be a very reliable source ofsafety for our customers. If there arises a problem with the enginerunning, the operator of the vehicle or equipment or a standby personcan remotely shut off the engine.

With the success of our patented wireless shut down switch for engineshas grown, more customers are now purchasing our units to be installedon new vehicles or equipment. With the new engines systems today, theyare either controlled by a computer or engine module. There is no easyway to connect our unit to the engines computer system without cuttingwiring or hacking into the computer system. These manufactures will notwarranty their products if the wiring has been cut or tampered with. Ourcustomers want our product attached to their truck or equipment but atthe same time are reluctant to cut up the wiring or do something thatmight damage the computer system. The customer would like to keep thefactory warranty intact, in case they ever have a problem in the future.Our customers have asked us to figure out a way to solve this problem.If we wanted to sell units and satisfy our customer base, we had to comeup with a simple solution.

We searched for a commercial solution already being manufactured, butdid not find one. What we did learn in our research, that mostmanufactures of vehicles and equipment were protecting their computersystem or engine modules by a fuse circuit controlled by the ignitionkey.

SUMMARY OF THE INVENTION

Aspects of this invention relate to disable an electrical circuit in amobile vehicle or equipment.

For example, this method will work for most vehicles or equipmentmanufactured today. Start the engine of the equipment to be controlled.Find the Battery/Ignition fuse in the fuse panel. While engine isrunning, remove this fuse. Engine will shut off.

Remove the Battery/ignition fuse from the fuse panel of the vehicle orpiece of equipment. It is normally 10-15 amperes. In this emptyBattery/Ignition fuse slot, plug in a “Littel Fuse” “add-a-circuit” part# 0FHM0200Z. This connector now as a place for 2 fuses. The first slotis intended for the original fuse that was removed, to be placed backinto this slot, thus completing the original fuse circuit. The secondslot is for a fuse which will power an additional circuit.

Instead of plugging in the original fuse in the first position, we havemanufactured a fuse like devise that plugs into this 1^(st) position.This devise has no internal fuse, but instead has 2 properly sized wiresfor the rated current of the original fuse. Each of these wires areconnected to the 2 terminals fuse ends respectfully. One of the wires isconnects to an inline fuse holder, and the other end of the fuse holderconnects to one main terminal of an automotive solenoid. The other wirecoming out of this fuse devise goes to the other main terminal of theautomotive solenoid. The original fuse that was taken out of the fusepanel is inserted into the new inline fuse holder.

By applying control power to the solenoid, this solenoid internallyenergizes ,connecting the 2 wires that are now connected to this fuselike devise in the “Littel Fuse” “add-a-circuit”, completing thecircuit. By removing control power from the solenoid, the circuit isdisabled.

Insert a properly rated fuse in the second position of the “Littel Fuse”“add-a circuit” slot. This fuse now powers the second circuit; which isconnected to our unit, which provides control power to the solenoid. Wecan now remotely shut off the engine with the Wireless Fox-Paws Models100-300 or our Fox-Paws corded Model 500 with the ignition key in the ONposition.

We have now made a circuit with the same rated capacity and fusing asthe original, but now have the capability of disabling the circuit asneeded. We had now solved the problem of installing our units on newvehicles or equipment without voiding the manufactures warranty.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 is an exemplary drawing of the mobile vehicle or equipmentelectrical circuit disabler. 101 battery/ignition fuse is removed from102 fuse panel. 103 Littel fuse “add-a-circuit” is plugged into the saidport of removed fuse 101. Manufactured device 104 is plugged into port 1of Littel fuse “add-a-circuit 103. Original fuse 101 is plugged intoinline fuse holder 105. The 2 said wires of manufactured device whichhas shut diode 106 attached the 2 wires respectfully are connected tothe 2 main lugs of solenoid 107 A & B. 7.5 amperes fuse 108 is pluggedinto port 2 of 103. Port 2 feed wire of little fuse “add-a-circuit” 103is connected to slip connectors 109. Slip connectors 109 is connected toslip connector 110. Slip connector 110 is connected to black wire ofcontroller Fox-Paws 111. Controlled white wire of 111 is connected tothe control terminal C of said solenoid 107.

FIG. 2 is an example of our new instructions for a typical installer ofFox-Paws shut down switch.

Directions to connect Fox-Paws to vehicle:

Step 1: Start engine. Remove fuse from ignition circuit. Make sure thisfuse stops the engine.

Step 2: Using VOM or test light with key in the on position, find portwith power in the fuse block. Make sure white dot on Add-A-Fuse terminalcorresponds to terminal with power.

Step 3: Plug in Add-A-Fuse circuit.

Step 4: Plug original fuse into black fuse port on wire harness.

Step 5: Connect wires to Cole Hersee Solenoid

Step 6: Plug slip connector of wire harness into slip connector ofFox-Paws unit.

Step 7: Connect ground wire of Fox-Paws to Cole Hersee solenoid base.

Step 8: Ground Cole Hersee solenoid to vehicle.

FIG. 3 is a drawing of the manufactured device 104. This drawing detailsthe 2 wires entering into the main body of said device connected to the2 terminals which plug into the fuse panel slots respectfully.

FIG. 4 is a flow chart describing the flow of electrical power from andreturning to the fuse panel 102. Power is taken from the fuse panel 102by way of Little Fuse “add-a-circuit’ 103. It is noted on FIG. 2, box10, that the polarity of Littel fuse “add-a-circuit” 103 has a white doton the top corner of this said piece. As per instructions Step 2 of FIG.2 the white dot corresponds to the terminal with power of fuse panel102. If 103 is placed backwards the circuit disabler will not workproperly. When 104 is installed into 103 the [Z] wire is the feed wire,corresponding to terminal with power of fuse panel 102. Said [Z] wire isconnected to an inline fuse holder 105. Fuse 101 is inserted into inlinefuse holder 105. Other end of inline fuse holder is connected to [R]wire to one side of shunt diode 106 and connected to B of solenoid 107respectfully. [P] wire is connected to [U] wire, which is connected tothe other side of shunt diode 106 and connector 107 A respectfully. Thisopposite end of [P] wire is connected to the return side of manufactureddevice 104. This return side of 104 is connected to the return side of103. 103 is connected to the return side of said fuse slot of fuse panel102.

Fuse 108 is inserted into the second circuit of Littel fuse“add-a-circuit” 103. [T] wire is connected to second circuit output ofLittel fuse “add-a circuit” and powers slip connector 109. Slipconnector 109 powers slip connector 110. Slip connector 110 powers Qwire to input of Controller “Fox-Paws” 111. G wire of controllerFox-Paws 111 is grounded to frame of said vehicle or equipment. Solenoid107 frame is grounded to said frame of vehicle or equipment.

When “Fox-Paws” 111 is in Green (go)mode, power will flow into W wirefrom Fox-Paws 111, powering terminal C of solenoid 107. When solenoid107 is energized, power will flow between connection A&B of 107, thuscompleting the circuit. (See Arrows of flow of power on FIG. 4) Engineof vehicle or equipment will start and run.

When “Fox-Paws” 111 is in the Red (stop)Mode, power flowing fromController 111 to terminal C of solenoid 107 will be shut off, thusdisabling the circuit between terminal A&B of solenoid 107. When poweris disabled between terminal A&B of solenoid 107, power flowing to andfrom Battery/Ignition circuit of fuse panel 102 will stop. Engine willstop. Engine will not start or run.
